PCA (Principal Component Analysis)
📰 Medium · Machine Learning
Learn to apply Principal Component Analysis (PCA) to reduce data dimensions for better visualization and understanding, a crucial step in machine learning and data science
Action Steps
- Apply PCA to a dataset using Python's scikit-learn library to reduce dimensionality
- Visualize the results using a 2D or 3D scatter plot to identify patterns and correlations
- Compare the explained variance ratio of different principal components to determine the optimal number of dimensions
- Use PCA to preprocess data for machine learning models and improve their accuracy
- Evaluate the impact of PCA on model performance using metrics such as accuracy and F1-score
